All deaths occurred in Pennsylvania, in worst year since 1992 for one of the most contagious diseases
Pennsylvania health officials said a fourth person had died of measles-associated illness in the worst year for the disease since 1992. All four US deaths have occurred in the state.
Due to the Trump administration changing how it reports measles deaths, the Centers for Disease Control and Prevention (CDC) does not count any of the deaths in its national tally. Three people died in 2025.
